Step 3: Update OneNote for Mac

We’re continuously making OneNote better, so it’s a good idea to check if you have the latest version of the app installed on your computer.

On the menu bar, click Help > Check for Updates.

In the dialog box that opens, select Automatically, and then select how often you want OneNote to check for updates from now on (Daily, Weekly, or Monthly).

Click Check for Updates.

Alternately, you can check for and get software updates for your Mac directly from the App Store. If updates were found for OneNote, please install them, and then try syncing again.
